Realistic Gym Mirror Selfie

A realistic smartphone mirror selfie of a {argument name="subject" default="woman in her early-to-mid 20s"} seated on a {argument name="prop" default="black gym bench"} inside a {argument name="location" default="contemporary fitness center"}. She sits slightly right of center in the vertical frame, leaning back casually, holding her phone in front of her face to capture the reflection. She wears a dark gray forward-facing baseball cap with long straight black hair flowing out beneath it. Her expression is detached and cool, eyes directed at the phone or mirror, lips lightly closed and partially obscured by the device — no smile, as if caught mid-rest after training. Her top is a black bandeau or single-shoulder strappy athletic piece, fitted with slight creasing and matte stretch texture, leaving collarbones, shoulders, and the tops of her arms bare. Her bottom is a black high-waisted mini skirt or skort, snug through the hips, with natural fabric folds near the thighs from the seated position. She wears tall brown boots. One leg crosses into the foreground while the other extends diagonally toward the lower-left corner, producing a strong diagonal line and subtle wide-angle distortion that elongates the legs. Skin tone is fair and warm ivory, naturally lit by cool overhead fluorescents but not plastic or retouched. Exposed areas include the neck, shoulders, collarbones, upper chest, both arms, hands, a sliver of waist, and significant portions of both thighs, knees, and lower legs. Background shows a modern gym: gray walls, dark gray tile flooring, black benching equipment, weight bars, a nearby workout bench to the left, and a large rounded-rectangular glass window behind her reflecting cool blue-white fluorescent light. Primary lighting is from wide overhead LED panels. Retain mirror scratches, glass glare streaks, mild exposure blooming, and slight image compression artifacts. Visual feel should mimic a real small-sensor smartphone wide-angle mirror selfie: vertical 2:3 or 3:4 frame, mid-height mirror viewpoint, subject shifted slightly right, legs reaching lower-left. Deep focus keeps both the figure and background gym equipment readable. Avoid polished studio aesthetics — preserve casual social framing, minor imperfections, background equipment clutter, accidental reflections, and authentic indoor digital grain.
